Subject aims expressed by acquired skills and competences

Student will be able to: - classify basic groups of the current and advanced materials for applications in electric engineering, micro-electronics and opto-electronics - apply basic theoretical knowledge on influence of composition and internal structure of material on physical, mechanical, electrical, magnetic and optical properties - define requirements for individual groups of materials, technology for preparation and further processing, realisation of electronic elements

Teaching methods

Individual consultations
Project work


The aim of teaching of the subject is to provide students with basic information about current and prospective materials, which are used in various fields of electrical engineering and micro-electronics. Individual categories of materials for applications in electrical engineering are the following ones: conductive materials (conductors, super-conductors, materials for contacts, thermo-electric conversion, resistance materials, solders), dielectrics, ferro-electric materials and insulating materials, magnetic materials (soft, hard, special - based on alloys of rare-earth metals and oxides) semiconductors for micro- and opto-electronics, solar cells, metallic glasses, liquid crystals, nano-materials.
